score: add a `--check` option
Now that the test suite runs vcsn score
to make sure it is not broken, it would be nice to make it as fast as possible. --check
should imply -r 1
, of course, but
- all the
repeat
should be reduced to 1 - possibly, if we can make the sizes as small as possible, that would be fine. e.g. 'a{500}' -> 'a{1}', etc.
